An elderly Petaluma man has been arrested selling fentanyl and ammo. Last month, officers were investigating 69-year-old Richard Crandall because they thought he was selling drugs. On February 24th, police searched his residence on the 100 block of West Street and found about three ounces of fetanyl along with ammunition, drug paraphernalia and other evidence. Because he is a convicted felon, Crandall is prohibited from possessing firearms or ammunition. Crandall was not present at the time of the search and was arrested a few days later back at his residence. During that arrest, cops found more evidence that Crandall was selling drugs.
